Effect of second phase and grain boundary precipitation characteristics on intergranular corrosion properties of 7050 aluminum alloy

Effect of second phase and grain boundary precipitation characteristics on intergranular corrosion properties of 7050 aluminum alloy

SEM，EBSD and TEM techniques were used to study the effects of grain boundary precipitation characteristics and the Fe-containing second phase（Al7Cu2Fe phase） formed under different aging regimes on the intergranular corrosion properties of Al-Zn-Mg-Cu alloys. The results show that the change rate of...
